Why Cant I Trade? - There would be 3 main reasons for this:
1) Your Profile/Inventory are set to private. Both need to be public for the bot to work.

2) You don't have any keys/gems to trade with or they are not tradeable as of yet. TF2 Keys and Gems have a 7 day cool down if you bought them from the market. CSGO keys have a 7 day cool down and only work if you bought them from the market, so don't buy them from game.

3) You have not had Mobile 2FA on your account for 15 days yet. Steam wont let you trade without one.
